as some (possibly many) have seen i've been doing very little for tank maintenance.
i'm curious about some things though.
i know i'm getting antsy about needing a large water change, ... and i'm wondering/thinking. (as i know i want a different substrate as well)
how difficult is it to change the substrate (going with removing the fish)... and changing to a dirt substrate.
i don't have a lot of fish (and temporarily could use a smaller container for them)
if i completely redo the substrate, how long could i expect to wait for things to get healthy enough again for the tank to handle the fish i removed ?
no other cleaning (just remove all the old & add new substrate)
-i have lots of sponge filters that are probably loaded with good bacteria
i could guess a regular period of waiting for cycling to take place, ... but that temporary home for 4-6 weeks, i'm not that patient by choice
otherwise test kits to wait for nitrogen cycle to complete ?
optimally a second tank to use, but i don't have that option at the moment.
